Hi, I am starting to see more frequent occurrences of a DatabaseModifiedError when users execute searches on my site. Since our index is being updated all the time, its easy to understand why these happen, but is it possible to ignore this error and execute the search against the stale revision? It's likely only a few seconds out of date, and if I follow the advice and reopen() the

I'm already retrying the ->get_mset operations; but now I'm wondering where I'd hit DatabaseModifiedErrors while inside a Xapian::MSetIterator loop. I assume ->get_document is a place where it gets thrown; but once a document is retrieved, can iterating through terms in one document (using TermIterator) also throw DB modified? I'm dumping multiple terms per-document to a

Hi there, My web app uses Xapian via the PHP bindings. I'm getting this error thrown occasionally when atempting to instantiate a XapianDatabase object for searching. DatabaseCorruptError: Expected block 107 to be level 1, not 0 Here's the line that invokes it: $database = new XapianDatabase(PROJROOT.'/data/xapian/posts'); And my version is xapian-core 1.2.3 with matchspy.

Xapian is a very excellent open source search engine library, but there is no native support for Chinese word segmentation in queryparser and termgenerator. Therefore, I modified small amount of source codes, integrated into the SCWS tokenizer, that is the same open-source and developped by myself. Anyone can obtain the patch from below URL. After patching, Xapian::QueryParser::parse_query and

Hi, I have previously had a problem with getting this error on a get_mset call, and solved it by subclassing XapianEnquire with a backoff-and-retry algorithm (as suggested by this list, many thanks!). However, I now get it intermittently when calling get_data on a XapianDocument. The same solution doesn't seem to be quite as easy in this case, because: 1. The document is not instantiated

Sorry if this is a repost .. I have edited my query a little bit and my previous post was too long and so was waiting approval(I cancelled it) Ok. Another question.. I have installed the Search ::Xapian on my local machine. Now I'm trying to install it on a machine where i dont have root access. So while running configure of the Xapian library I gave the -prefix option and everything installed

Hi all, Currently I'm implementing a retrieval system with multiple reader processes and only one writer process updating the database periodically. In a reader process, whenever a Xapian::DatabaseModifiedError exception is caught, I call function reopen() and retry. However, my problem is, when there is only a small set of modification, e.g. only one new document is added, the reader would

Ocassionally when I'm searching using Omega I get: "DatabaseCorruptError: Cannot open tables at consistent revisions" If I click reload it's all ok, is this the database being updated?, is there a way to avoid the message? Frank

Hello, I am trying to rebuild an index of 2+ million documents and have not been successful.

Hello, I noticed a problem with DatabaseCorruptError exceptions with public-inbox and I guess it's user error... The problem is public-inbox was calling replace_document to modify the DB while iterating through a PostingIterator. At first I thought it was a glass problem, but I've hit it with chert on my dataset, too. I have a standalone Perl script to reproduce the problem at

I am getting this error when trying to remove a document from my Xapian database via writabledatabase_delete_document: "DatabaseCorruptError: Db block overwritten - are there multiple writers?" There might have been two processes trying to write to it earlier today, but currently only one process can touch it at a time, and I still receive the error. Is there a fast way to fix this
